Hi C.
Sorry you have to go through this...I did too. With my first, I failed the 1 hour, then passed the 3 hour. With the second, I failed the 1 hour and failed the 3 hours. Nothing was different about the pregnacies up to that point.
What I learned, is that they are really liberal on the reading of the results. Many ppl pass, who should have failed. Normal blood sugars are between 90 to 120. When measuring for gestational diabetes, they give you up to 140. So really, a fail by a few points is really a fail by over 20something points. I don't know why they give the higher range on the test, if you fail you have to keep it under 120 through eating habits or they will put you on insulin.
When I found out I had gd with my second, I was devastated. It wound up being the best thing that could have happened to me. It forced me to eat correctly during the pregnancy. While I have never been overweight, I used to be really athletic, I never understood how the body uses food. The class really taught me how to eat correctly and monitoring my blood ranges showed me exactly how food was affecting me.
After having it dx w/my second I am convinced that I had it with my 1st as well...that the test was too broad. I felt so much healthier at the end of my term with my second. I still had energy, I was breathing easier, the 3rd trimester was just sooo much easier.
As much as it sucks to go in for it, I have fasting and getting pricked, its probaly for the best. Even though you are a healthy weight, you are getting older and your body might be reacting differently. I understand why the practice wants you to get checked. If you were to have it, and not taking the proper measures to monitor it, the baby's health would really be at risk.
If you do have it and you need someone to talk with or help figuring out the diet, please feel free to contact me
